Abstract (en)
[origin: EP3671891A1] Provided are a battery pack and an electrical apparatus by which information can be transmitted at an appropriate timing from the battery pack to a device body. A battery pack 10 comprises: a serial communication reception circuit 31 and a temperature information transmission circuit 32; an LS terminal that is selectively connected to the serial communication reception circuit 31 or the temperature information transmission circuit 32; a first switching circuit 21 that is provided between the LS terminal and the serial communication reception circuit 31 and the temperature information transmission circuit 32; and a V terminal that is connected to the first switching circuit 21. The first switching circuit 21 switches between connecting the serial communication reception circuit 31 or the temperature information transmission circuit 32 to the LS terminal according to a signal inputted from the V terminal.
